Answer:
i₃ > i₁ > i₂
Explanation:
For this exercise we use the resistance ratio
R = ρ
where ρ is the resistivity of the wire, in this case it is the same for all three cases, l the length and A the area of the wire.
We have three cases
a) length l = L
area A = A
b) length l = 2L
area A = A
c) length l = L
area A = 2A
we calculate the resistance for each case
a) R₁ = ρ L / A
b) R₂ = ρ 2L / A
R₂ = 2 ρ L / A
R₂ = 2 R₁
c) R₃ = ρ L / 2A
R₃ = ½ ρ L / A
R₃ = 0.5 R₁
therefore when the connect of the circuit is carried out we can use ohm's law
V = i R
i = V / R
whereby
a) i₁ = V / R₁
b) i₂ = V / 2R₁
i₂ = ½ i₁
i₂ = 0.5 i₁
c) i₃ = V / 0.5 R₁
i₃ = 2 I₁
the order from highest to lowest in the current is
i₃ > i₁ > i₂
Applying the concept of scalar product. We know that vectors must be multiplied in their respective corresponding component and then add the magnitude of said multiplications. That is, those corresponding to the component are multiplied with each other, then those corresponding to the component and so on. Finally said product is added.
The scalar product between the two vectors would be:
Therefore the scalar product between this two vectors is 5.74
The phenomenon that best illustrates on matter behaving like a wave instead of being a particle is called the interference patterns of electrons. In addition, this phenomenon was described by experimenting that made use of an electron wherein the wave nature of electrons was observed.
I think c Is the right answer or it could be b
Hi!Schrodinger equation is written as HΨ = EΨ, where h is said to be a Hamiltonian operator.
